Wayne Dalton’s Model 926 rolling service door is an economical solution for protecting facility openings. Composed of flat-faced slats that provide a natural watershed, this model helps reduce corrosion. They design slats with free-acting interlocking joints that permit easy articulation when the door coils.
Model 926 features a strong double-angle bottom bar that reinforces the lower edge of the curtain against wind pressure. It also permits varied lock, astragal, and safety edge options. It does not require fasteners in the guide openings, so the bottom bar does not interfere with door operation. Zinc-plated, cast iron wind locks add strength and prevent lateral slat movement.
The counterbalance assembly comprises a spring barrel that serves as a load-carrying beam. It encases the counterbalance mechanism and provides the axis around which the curtain coils. (Deflection is limited to 0.033 inches per lineal foot of span.)
